Publication number: 20200358418Abstract: A microwave generation system comprising a microwave generator, a pulse generator and an impedance network. The pulse generator is arranged to provide pulses of electrical power to the microwave generator and is operable to vary the power of the pulses of electrical power which are provided to the microwave generator. The impedance network is connected between the pulse generator and the microwave generator. The impedance network is switchable so as to substantially match an impedance across the pulse generator according to variations in the impedance of the microwave generator.Type: ApplicationFiled: October 10, 2018Publication date: November 12, 2020Applicant: Teledyne UK LimitedInventors: Mark ISKANDER, David ROWLANDS

Patent number: 9717651Abstract: A pill crushing apparatus for use with first and second nestable cups comprising a first cup holder which is moved linearly toward a second cup mounting surface holding a second cup. The first cup holder rotates relative to the rotationally fixed second cup. During the crushing process, the pills first may begin to crush against the linear load being applied thereto, and thereafter grind into a fine powder due to the rotational force of the first cup against the second cup. The first cup and second cup have different sidewall angles to promote pill crushing while inhibiting migration of the crush material to prevent the crushed material from reaching the open gap between the top perimeters of the nesting cups. Each cup includes a plurality of lugs having a curved profile configured to engage respective recesses on the cup holders. Each cup is fabricated through thermoforming or vacuum forming techniques.Type: GrantFiled: March 21, 2014Date of Patent: August 1, 2017Assignee: First Wave Products Group LLCInventors: Brian Hohl, Brian D. Bell, Douglas Dufaux, David Rowlands

Patent number: 7270821Abstract: The hepatitis B virus (HBV) capsid is made up of a single species of protein called the core antigen (HBcAg) which self-assembles into particles. The particles are highly immunogenic and are able to present heterologous epitopes to the immune system when the epitopes are inserted into a surface-exposed region of the particles called the “e1 loop”. The structural building blocks of the particles are tightly associated dimers of HBcAg in which the adjacent e1 loops are closely juxtaposed. It is proposed that sequences inserted into the e1 loop are conformationally restrained in the assembled particles when presented in monomeric core protein. The invention seeks to solve this problem by covalently linking core proteins as tandem copies (e.g., as dimers) so that insertions can be made independently in each copy.Type: GrantFiled: April 9, 2001Date of Patent: September 18, 2007Assignee: University of Leeds Innovations LimitedInventors: Annick Gehin, Robert Gilbert, David Stuart, David Rowlands

Patent number: 6223513Abstract: An exemplary embodiment of the present invention is a flyer bow having a first surface and a second surface in opposition to the first surface. The first and second surfaces are joined to form an airfoil shape. A channel passes through the flyer bow between the first and second surface and a wire guide is disposed within the channel. There is at least one orifice through one of the first and second surface thereby establishing fluid communication between the channel and the ambient atmosphere.Type: GrantFiled: November 24, 1999Date of Patent: May 1, 2001Assignee: Kamatics CorporationInventors: Jeffrey M.

Patent number: 6173420Abstract: A method and apparatus for configuring a software application on a cluster is provided. A configuration coordinator executing on a configuration manager communicates with one or more configuration slaves executing on a set of nodes that are operating as a cluster. The configuration coordinator sends messages to the one or more configuration slaves to initiate a configuration operation for a software application. Each configuration slave automatically performs a series of actions to configure the node on which it resides. When all the nodes complete the configuration operation for the software, the process is complete. While performing the series of actions, the configuration slaves generate logs that reflect their progress in performing the series of actions. If a problem occurs during performance of the series of actions, the configuration slave that encounters the problem indicates to the configuration coordinator that an error occurred.Type: GrantFiled: October 31, 1997Date of Patent: January 9, 2001Assignee: Oracle CorporationInventors: Ramu V.
